Hi!
Here's a custom action I coded thats a variation of the Get Angle To Target action but stores Signed Angle to know if the Target is right (positive) or left (negative) from the GameObject's forward axis:
/ * Get Signed Angle to Target - Playmaker Custom Action
* https://github.com/pedrosanta/PlaymakerActionsPack */
using UnityEngine;
namespace HutongGames.PlayMaker.Actions
{
[ActionCategory(ActionCategory.Transform)]
[Tooltip("Gets the signed Angle (in degrees, clockwise, -180 to 180) between a Game Object's forward axis and a Target. The Target can be defined as a Game Object or a world Position. If you specify both, then the Position will be used as a local offset from the Object's position.")]
public class GetSignedAngleToTarget : FsmStateAction
{
[RequiredField]
public FsmOwnerDefault gameObject;
public FsmGameObject targetObject;
public FsmVector3 targetPosition;
public FsmBool ignoreHeight;
[RequiredField]
[UIHint(UIHint.Variable)]
public FsmFloat storeAngle;
public bool everyFrame;
public override void Reset()
{
gameObject = null;
targetObject = null;
targetPosition = new FsmVector3 { UseVariable = true};
ignoreHeight = true;
storeAngle = null;
everyFrame = false;
}
public override void OnLateUpdate()
{
DoGetAngleToTarget();
if (!everyFrame)
{
Finish();
}
}
void DoGetAngleToTarget()
{
var go = Fsm.GetOwnerDefaultTarget(gameObject);
if (go == null)
{
return;
}
var goTarget = targetObject.Value;
if (goTarget == null && targetPosition.IsNone)
{
return;
}
Vector3 targetPos;
if (goTarget != null)
{
targetPos = !targetPosition.IsNone ?
goTarget.transform.TransformPoint(targetPosition.Value) :
goTarget.transform.position;
}
else
{
targetPos = targetPosition.Value;
}
if (ignoreHeight.Value)
{
targetPos.y = go.transform.position.y;
}
var localTarget = go.transform.InverseTransformPoint(targetPos);
// This will only work with vectors on XZ plane, so ignore height is irrelevant. Update description/etc asap.
storeAngle.Value = Mathf.Atan2(localTarget.x, localTarget.z) * Mathf.Rad2Deg;
}
}
}
Additionally I am maintaining a custom actions repository on https://github.com/pedrosanta/PlaymakerActionsPack (https://github.com/pedrosanta/PlaymakerActionsPack). Feel free to fork it away and collaborate. :)
Cheers.
